This is one of a type of strip from around this time where Snoopy is attacked by some mechanical device that he fails to understand. These strips rely on the dog being naive on the subject of human invention, which requires a certain flexibility of characterization.
Remember, this is the same dog that lives in a duplex and has been seen with a TV aerial atop his house. But Snoopy is used here more for being a dog than for being Snoopy. Later, when his personality becomes less doglike, these jokes will make less sense.
